South Park‘s deep-voiced Chef, Isaac Hayes, is being treated at an undisclosed Memphis hospital for exhaustion.

“He’s just overworked and had been in Atlantic City performing, the D.C. area performing, and in Tunica (Miss.) a couple of nights ago. He was just overworked,” his longtime songwriting partner, David Porter, tells the Commercial Appeal newspaper, adding: “He’s doing much better.”

Besides his popular gig on the satiric Comedy Central animated series, Hayes, 63, is best known for his 1971 No. 1 hit “Theme From Shaft,” from the Richard Roundtree film. The soundtrack won the Oscar for best musical score.
